Weigh service requests and handling time against the portal investment – and see after how many months your customer portal pays for itself.
Customer portal ROI calculator
The Customer Portal ROI calculator provides an immediate, non-binding economic estimate without requiring an email address or registration. It separates investment and recurring effects and uses documented assumptions derived from more than 250 software projects.
Use the calculator right below for an instant first estimate – no sign-up and no fixed-price commitment. We align scope, risks, and assumptions in a conversation before a binding quote.
The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.
1. Capture inputs
The calculator records the visible project, volume, complexity and operating parameters selected on this page.
2. Add fixed components
One-off investment and recurring operating components are added separately.
3. Apply multipliers
Volumes, time values and rates are multiplied where the model converts effort or incidents into monetary effects.
4. Create the range
The calculator applies its documented lower and upper uncertainty factors to the base result; ROI views keep investment and savings visible separately.
5. Round and calibrate
Monetary result fields are rounded to the nearest whole euro. Public project-cost components are calibrated with the centrally maintained display factor.
6. Classify the result
The result is shown as non-binding guidance. A binding quote requires scope, data, integrations, risks and acceptance criteria to be reviewed.
Efficiency or discount factor: A central display factor of 0.7 is applied to public project-cost components to keep all calculators aligned with the currently reviewed pricing basis. It is not a customer-specific discount; customer-entered wages, revenues and existing operating costs are not reduced.
Why this is not a binding quote: The calculator cannot verify complete requirements, third-party dependencies, data quality, legal constraints or acceptance criteria.
Costs for Customer Portal ROI depend on scope, risk, and quality expectations. The calculator provides an initial range.
We quote transparently with dedicated contacts from East Frisia.

FAQ
The calculator compares the portal investment with the saved service minutes: routine requests such as order status, invoice copies or document downloads are answered by customers themselves in the portal.
Depending on the self-service rate (30–60%), a large share of calls and e-mails disappears – resulting in the break-even in months.
Recurring standard requests have the biggest impact: delivery status, invoice and document copies, master data changes, ticket status and order history.
Rule of thumb from our projects: whatever your back office reads out of a system via copy-paste today, a portal can display directly.
At medium request volumes, break-even typically lands between 6 and 15 months – from saved handling time alone.
Faster answers around the clock and relieved service teams come on top as unquantified benefits.
Calculate your portal ROI
We analyse your request volume and produce a solid ROI assessment including a portal concept.
Typical project values from our customer portal work: login area, documents, order status and ERP integration – from around EUR 15,000 for focused portals up to EUR 40,000 and more with many processes and systems, excl.
VAT.
Conservatively excluded: higher customer satisfaction through 24/7 availability, fewer errors through self-entry instead of phone transmission, additional revenue via reorder functions and relief for sales, who answer fewer status questions.
Adoption.
A portal only saves money if customers use it: simple login, real value from the first visit and active communication at launch. Portals that are merely a document archive stay empty – requests then continue via phone and e-mail.
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.
The ranges shown are indicative. For a binding quote we discuss scope, priorities and funding options in a free intro call. Many digitalization projects qualify for grants – try our funding calculator.

When does your customer portal pay for itself?
Interactive estimate based on your inputs.
Non-binding project range from the software cost calculator: EUR 10,332 – 372,623 excl. VAT.
Methodology: The estimates are based on historical project data, complexity drivers and standard implementation assumptions. Results are a non-binding indication only; effort and price must be calculated individually.
